RAIL-JOINT.

Specification of Letters Patent.

Patented Aug. 6, 1907.

Application filed December 22,1906. Serial No. 349,114.

To all whom it may concern:

Be it known that 1, James B. BAUM, a citizen of the United States of Ainerica,'residing at Grand Junction, in the county of Mesa and State of Colorado, have invented new and useful Improvements in Rail- .loints, of which the following is a specification.

This invention relates to rail joints, and one of the principal objects of the same is to provide strong, reliable and eflicient means for firmly uniting the meeting ends of railway rails to prevent spreading or creeping of the rails at the joint.

Another object of the invention is to provide simple and reliable means for preventing the movement of the meeting ends of railway rails, and to provide a chair for the rail flange in two parts which will effectually prevent spreading of the rails.

These and other objects may be attained by means of the construction illustrated in the accompanying drawing, in which:

Figure 1 is a side elevation of the meeting ends of a pair of railway rails joined in accordance with my invention. Fig. 2 is a side elevation of the inner side of one of the fish plates. Fig. 3 is a longitudinal sectional view of the sectional. chair. Fig. 4 is a vertical sectional view on the line 44, Fig. 1.

Referring to the drawing for a more particular description of my invention, the numerals 1, designate the meeting ends of a pair of railway rails, and 2 are the fish plates, provided with a longitudinal groove 3 upon the inner surface and provided with a recess 4 at their lower edges, said recesses terminating in shoulders 5 near the opposite ends of said fish plates. The rail chair consists of two sections 6 and 7, the section 6 being provided with a tongue 8 which fits within a socket 9 in the member 7. The rail chair members 6, 7 are provided with flanges 10 which extend over and fit the upper surface of the flange 11 of the rail and terminate in upwardly extending flanges 12 which fit within the recess 4 in the fish plates 2, the ends of the flanges 12 resting against the shoulders 5 at the opposite end of said recess. The fish plates 2 fit snugly under the head of the rails 1, and bolts 13 securely hold the fish plates in place.

From the foregoing it will be obvious that the fish plates 2, being held securely in place by means of the bolts 13, and the chair members 6 and 7 being held firmly to the fish plates by means of the recess 4 and the shoulders 5, all parts of the rail splice are held against movement either longitudinally or transversely, and that the rails can be quickly secured together and will be held rigidly by the sectional chair and the fish plates made in accordance with my invention.

ISI

1. A rail joint comprising fish plates, each having a recess at its lower edge, and shoulders at the opposite ends of said recess, and a sectional rail chair fitted in the recesses in the fish plates with the ends of said chair fitted in the recesses against the shoulders, substantially as described.

2. A rail joint comprising a rail chair made in sections, one of said sections provided with a tongue and fitted within a socket in the other section, and a pair of fish plates each provided with a longitudinal groove and with a re cess at the lower edge, and shoulders at the ends of said recess, the ends of said chair being fitted against the shoulders at the ends of the recesses in the fish plates and bolts passing through said fish plates and through the webs of the rails, substantially as described.

3. A rail joint comprising a rail chair made in sections, one of said sections having a tongue extending into a socket in the other section, flanges to engage thebase flange of the rail, and upwardly projecting lugs disposed upon opposite sides of the web of the rail, and fish plates each provided with a longitudinal groove upon its inner side, and a longitudinal recess at its lower edge to engage the flange of the rail chair section, and shoulders at the ends of said recess against which the ends of said flanges abut, and bolts passing through the fish plates and through the webs of the rails, substantially as described.

In testimony whereof, I affix my signature in presence of two witnesses.
